United States atent TRAVELER WITH FACING SHELL OF WEAR RESISTANTMATERIAL Louis H. Morin, Bronx, N.Y., assignor to Coats & Clark Inc.,New York, N.Y., a corporation of Delaware Filed July 23, 1959, Ser. No.828,990

10 Claims. (Cl. 57-125) This invention relates to travelers formed frommolded plastic material employing on the undersurface of the large hookend portion of the traveler a facing shell of wear resistant material.More particularly, the invention deals with a structure of the characterdescribed, wherein the traveler is formed with a recess of predeterminedcross-sectional contour on the undersurface of the large hook end of thetraveler, into which recess the wear shell, element or member is snuglyarranged.

Still further, the invention deals with a structure of the characterdescribed, wherein means is provided for retaining the shell againstdisplacement from the recessed portion of the traveler.

The novel features of the invention will be best understood from thefollowing description, when taken together with the accompanyingdrawing, in which certain embodiments of the invention are disclosedand, in which, the separate parts are designated by suitable referencecharacters in each of the views and, in which:

Fig. l is a side view of a part of the large hook end portion of atraveler on an enlarged scale and illustrating one of my improved wearresistant shells thereon, with part of the construction broken away andin section.

Fig. 2 is an enlarged section on the line 2-2 of Fig. 1.

Fig. 3 is a diagrammatic perspective view of one end portion of a wearresistant shell detached.

Fig. 4 is a view, similar to Fig. 2, showing a modification; and

Fig. 5 is an outside view of the upper end portion of one wall of theshell shown in Fig. 4, detached.

In view of the fact that travelers are generally known in the art, tosimplify the illustration in the accompanying drawing, the large hookend portion only of the traveler is shown. The traveler is molded fromsuitable plastic material such, for example, as nylon and, in themolding operation, a recess is formed on the inner surface 11 and sidesurfaces 12, as clearly shown at 13 in Fig. 2 of the drawing. The recess13, arranged in the side walls 12, terminates at upper ends in inwardlyextending grooves or indentures 14, having surfaces 15 arranged at rightangles to the sides 12 and surfaces 16 arranged at an angle thereto,thus fashioning the grooves 14 to substantially triangularcross-sectional contour.

At 17 is illustrated one of my improved wear resistant members orelements in the form of a substantially U-shaped shell, the thickness ofwhich corresponds to the depth of the recess 13, so that, when the shell17 is in operative position, as shown in Fig. 2 of the drawing, outersurfaces of the shell will be flush with the surface 11, as well as theside surfaces 12.

The ends of the side walls 18 of the shell 17 terminate in inwardlyextending flanges 19 which are adapted to enter the grooves 14, asclearly noted in Fig. 2 of the drawing. it will also appear, from aconsideration of Fig. l of the drawing, that the ends of the shell 17fit snugly within the walls 26 of the recess 13, thus definitelypositioning the shell 37 on the hook end portion.

Patented Jan. 24, 1961 The member, element or shell 17 can be composedof any suitable wear resistant metal and, with the structure shown inFigs. 1 to 3, inclusive, it is preferred that the metal will have springproperties, so as to enable the side walls 18 to be flexed apart inmounting the shell in the recess 13. The shell will be so tensioned asto urge the walls 18 firmly upon the walls of the recess 13, with theflanges 19 fitting freely, but snugly, in the grooves 14. Whenassembled, it will appear that the shell is fixedly retained againstmovement and/ or displacement from the hook end 10. However, if desired,the shell can be forcibly removed for replacement.

In Figs. 4 and 5 of the drawing, I have shown a modilied form ofconstruction, wherein the shell 17 or the side walls 18' thereof,instead of terminating in the flanges 19, include, adjacent their freeends and at corner portions thereof, indentures, countersunk sections orareas Zl, note Fig. 5 of the drawing. With this construction, it will beapparent that the recess 13 formed in the hook end 10', instead ofterminating in the grooves 14, will have two apertures formed therein,one of which is indicated at 22 in Fig. 4 of the drawing, and each ofthese apertures will terminate at the recessed sides of the traveler inbevelled wall portions 23 to accommodate the countersunk portions 21 ofthe shell 17, as clearly illustrated in Fig. 4 of the drawing.

With this construction, after the shell 17 is positioned on the travelerin the recess 13', rivet pins are arranged in the apertures 22, one ofthese pins being shown at 24 in Fig. 4 of the drawing, and the ends ofthe pins are headed-over, as seen at 25, into the countersunk portions21, so as to maintain the heads flush with the outer surfaces of thewalls 18.

With the structure shown in Figs. 4 and 5 of the drawing, the wearresistant member, element or shell 1! can be formed of materials whichdo not necessarily have spring properties and are otherwise secured inposition by the rivets employed, the shells being shaped to snugly fitin the recess 13'.

With both forms of construction shown, it will be apparent that aminimum amount of the material of the traveler is removed for receptionof the wear resistant element, thereby maintaining the desired strengthin the hook end portion of the traveler.

It will also be apparent that the U-shaped casing aids in reinforcingthe traveler and this is particularly true with the structure shown inFig. 4 of the drawing, where the side walls of the shell are securelybound and held upon the sides of the traveler by the rivet pinsemployed.

It will be understood that the angular surfaces is of the grooves 14 aidin positioning the flanges 19 in the grooves 14 in assemblage of theshell 17 with the traveler.
